1.5 hours. it is about a 2 mile walk. take your time it is beautiful!
An hour to two, depends how many times you stop and take in the calmness of each garden especially the flat garden.. also takes a bit longer if you stop for Sake at the cafe in a rain storm. Don't rush it.
Stop for lunch outdoors, it's great
1 to 2 hours
If the "house" on the grounds is still closed I'd say a bit less than 1.5 hours, even if you take your time and listen to the audio tours. If that house is open you could spend another half hour there.
The garden walk is just under a mile with plenty of places to rest and enjoy the beauty. Take water with you and enjoy! Great couple of hours of peace and nature.
Personal choice really, the walk uninterrupted might take an hour but to admire it, could take more. Best if you stick around and admire nature
